'root ARRANGEMENT.

Application filed ii rn- 19, 1927. Serial No. 184.898..

This invention relates to improvements in tool arrangements; one of the objects of the invention is to provide a tool arrangement for dies wherein the latter "can be moved t a limited extent "in any. direction at right angles; to their axes; This adjustability, when there' are a plurality of-dies in one shoe 'or dieplate, eliminates thenecessity of such accurate boring and reaming ofthe shoes or die' plates, Again lateral adjustment and resetting of dies is thereby made wit ordinary dies. For dies must be setwithin very close limits with respect to one possible in a short time, whereas this could onl be accomplished. with extreme difiiculty another, and the lateral adjustability' of tools constructed according to this invention eliminates a great deal of skilled labor which requires considerable time for its accomphshment.

Another object of the. invention is to pro-- vide a tool arrangement for a 'die having holding means for the die itself so constructed'that the latter may be simply and easily inserted into or removed' from its supportlng parts supporting arts may. also be'so constructed that they will various sizes; and again the supportin parts themselves can be readily removed from their shoe or die plate and others readily substituted if desired.

A. further object of the invention is to pro-- vide a tool arrangement which can also be applied to drilling jig bushings, "so that-the latter may be moved with respect to one another at right angles to their axes in any direction, thereby facilitating lateral adjust ment, and simplifying accurate manufacture.

-Having thus broadly outlined the major objects of the invention,'I will now proceed to describe embodiments thereof, with the aid of the accompanying drawings, in which both upper and lower die parts, hereinafter referred toas punches and matrixes respectively, are shown supported thereby, and also showing the adaptation of the invention to drilling jigs.-

In the drawings: I s Figure 1 illustrates a sectional elevation of the tool arrangement with a punch and punch matrix concentrically supported in their shoes. 1 U I Figure 2 shows a similar view of the upper tool arrangement with a smaller at any time Moreover the satisfactorily hold dies' of.

' hole 2, and in any direction,

tance between the axes of the hole 2 and the supported thereby and the latter' turned through one degrees.

Figure 3shows a similar view with the tool parts so turned that the punch and -1natrix are'jeccentric in their shoes.

hundred. and eighty -Figure 4 is a section on the line 44'.of I

Referring to the drawings, 1 designates 's a section on the line 5- 5 of lar hole 2 therein of uniform diameter throughout its depth. In this hole a split sleeve 3 having a tapered eccentric bore 4 is placed. A tapered socket "5 is positioned in the said eccentric-bore 4, and the socket is in turn provided with an eccentric opening 6 therein to receive the punch shank 7.

to coact with a similarly shaped end 9 of the punch body 9. ,In this manner the socket provides bearing surface forthe upper ends of punch bodies of various sizes as shown in Figures '1 and 2, and evenly an upper shoe having a substantially circu- The outer end of the socket ispreferably, provided with a conical bearing surface 8' transmits upward pressure exerted on the punch to the socket which .is in turn forced more firmly .into engagement with the sleeve 3.. v

It will be ndted that the eccentricity of the opening 6 in the socket 5 is preferably equal to. the eccentricity of the b'ore4 in the sleeve 3, so thatthe sleeve and socket can be so .t'urned with respect to one another that the eccentricity of the sleeve bore offsets. the

eccentricity of the socket opening, thereby bringing the shankof the punch concentric with the hole 2 inthe upper shoe. Again the sleeve and socket may be so turned with re spect to one another that the punch shank may be set. at

until the dispunch shank is equal to twice the eccentricity of either the sleeve bore with regard to the peripheryiof the sleeve, or the socket opening with regard to the periphery of the socket. I

Similarly in the lowershoe 1. is a hole 2" having a split slee've3 therein, the bore 4" any desired eccentricity to the 5 are generally provided in the outer end of the socket 5, or 5, in-order that the latter may be readily turned.

A passage 12, or 12 may be provided from the inner end of the hole 2, or 2, to the opposite side of the shoe 1, or 1. In the case of the socket 5 a knock-out plate 14 bears on the inner end of the socket so that by striking the plate the socket may be driven out of engagement with the tapered bore 4 of the sleeve.3. And in the case of the socket 5 the latter is usually provided with an internally threaded portion 6? of reduced diameter below theshankfl This threaded portion is adapted to receive the enlarged threaded end 14 of the knock-out punch 14" after the shank 7 of'the matrix 8 has been removed from the o ening 6*. So that by striking the end of t e punch 14 the socket aimaybe driven-out of the tapered bore 4 of the sleeve 3.

Inthe inner end of the socket 5. is a counterbore to receive a substantially circular member 15 having a downwardly projecting apron 16 around the -lower portion of which latter is a groove 17. The member 15 usually terminates at its upper end substantially flush with the upper end of the socket and is held in position in the latter as by radially disposed pins 18 which pass .through the upper annular portion of the socket. The shank 7 has a transverse slot 19 cut in it intermediately of its length, and

ositioned under the 20 designates a latch member 15. Around t e groove 17 and the latch 20- is a spring 21 which forces the bearing surface 22 of the latch into engagement with the slot 19 as soon as the shank is sopositioned that the latch bearing face can engage it. In order to facilitate the insertion of the shank 7 into the opening.6 the upper end of the'former may be bevelled towards the side in which the slot 19 occurs as indicated at 23, as this bevelled portion forces the latch gradually back against the tension of the spring 21 -as the shank is pushed upwards in the socket, and as the slot in the shank comes opposite the latch the bearing surface of the latter is moved into engagement with it by the said spring.- In order to remove the punch it is only necessary to turn it until the slot is free of the latch, and; the latter is forced back by the pe'ri hery of the shank against the tension of t.e spring. Whenfthis has SllI'- that the general arrangement is almost identical with the arrangement of the matrix 8. The jig is provided with a plurality of holes, one of which 25is shown. Into the latter a split sleeve 3 is inserted. The bore of the latter is eccentric and tapered to receive a socket '5 the periphery of which latter is correspondingly tapered. This socket has an eccentric opening 6 therein to receive the shank 7 of the bushing 8 The bore of I the latter is preferably concentric with the periphery of the shank, and the opening 6 in the socket is preferably uniform throughout its length. Obviously adjustment of the bushing at right angles to its axis is ob-' I tained by turning the sleeve 3 and the socket 5 either independently or together. 26 and 27 designate a drill and the work respectively.

The methodbf adjusting tool laterally is to turn the sleeve and socket? either together or independently before the socket is driven up tight 'into the sleeve in the positions shown in the drawings. 1 i

From the foregoing it is believed that the method of construction and application of the toolarrangement will be readily understood. Moreover While the preferred arrangement and a plieations of the invention have been descri ed and shown it is under-- stood that modifications ma in both with regard to tide specific tools shown and also to enable this tool arrangement to be applied to other specific uses.

What I claim is:

be made there-- 1. In a tool arrangement, the combination of a socket member having an opening therethrough, said socket member being counterbored from end, a member fixed in said counterborehaving a depending apron, a' tool, a shank on said tool in said opening having a slot substantially at right angles to its axis, a latch in said socket movable substantially at right angles to the axis of the latter, said apron preventing rotation of said latch in said socket, and s ring means tending to hold said latch in sai socket slot.

2. In a tool arrangement, the combination with a plate having a hole therein, of a split sleeve in said hole having an eccentric tapered bore, a socket having its periphery of said tool adjacent to its shank being tapered to coact with said countersunk socket portion so that pressure against the operat-' ing end of said tool exerts upward pressure on said socket forcing it into closer contact with the sleeve bore and causing the sleeve to ex and and grip the wa ll .of the hole in the pate, and means at the exposed end of the sleeve and socket for turning them to set the' eccentricity of said tool and the direct-ion of said eccentricity with regard to the hole in said plate. Y Y

3. In a tool arrangement, the combination with a plate having a larger hole therein,

anda smaller hole connecting the larger hole with the opposite side of said plate, of a split sleeve in said larger hole havin an eccentric tapered bore, a socketin said ore having its periphery tapered to coact with it and an eccentric opening therein the axis of which is arallel with the axis of said sleeve pe'rip ery, said eccentric opening being countersunk at its lower end, aplate I resting on said socket andextending over said socket opening under the smaller hole into closer contact with .the sleeve bore and causing the sleeve to expand and grip the' late, and means for turning said sleeve and socket at wall'of the larger hole in the their lower exposed ends so as to set the eccentricity of said tool and the direction of said eccentricity with regard to the hole-in the split sleeve.
